poration of New Hampshire v Application December29, 1939, Serial No. 311,474 I 13 Claims. (01. 19-158) This invention relates to a "mechanism :for

forming dye packages consisting of unspun sliver .cross wound upon' a flanged perforated dye spool. ThelUnited States patent of Edward J. Abbott, No. l,797,393, discloses and claimsv an" apparatus of the general type "to whichthis invention relates and on which this invention is an improvement.

Other objects of invention andfeatures of advantage and utility will be apparent from this specification and its drawings wherein the invention is explainedby-way of example. 7 Referring to the drawings:

Fig. 1 is a side elevationof a sliver gilling and winding machine embodying the present invention;

Fig. 2 is aplan view of part of the mechanism. ofFig. 1; Fig. 3 is a vertical sectional view on the line 33 ofFig.2; and g f v I i Fig. 4 is a fragmentary "plan view partly in horizontal sectionand to a larger scale, of one; of the supports for, the. winding" spool, and of mechanism associated therewith. The machine shown by way of example in the present drawings includes, like the machine of PatentNo. 1,797,393, the usualrear draft rolls 4, fallers G and front draft'rolls ,5, acting to draw out the sliver and bring its fibers into parallel relation. The front draft rolls 5 are preferably providedflwith the usual endless apron II. From thefront draftrolls, the drafted sliver passes to guide trumpets, one of whichis indicated at in Fig. 2, this trumpet preferably being oscillated by means of a pulley l8 aboutwhich is wrapped one run of an endless cordl9 passing around pulleys mounted upon a reciprocating carriage; The other run of thec'ord' I9 is fastenedia't a" suitable, point. to' the frame of. the machine, othat reciprocation of the carriage moves the run of the cord that engages the trumpet'pulley' l8, thus'oscillating the trumpet.

A horizontal shaft 2| carries a Dackagedrivej drum '24 having a corrugated surface, on which rests theflanged perforated dye spool 66 upon which is wound 'gilled sliver, the drum being splined to the shaft 2|; The shaft 2i isdhvhf by a gear 26 meshing with an idler gear" 21 which'is driven by a gear 28 -secured to the end ofthe shaft 5* which carries, the front bottom draft roll 5. The carriage indicated generally at-30 is slidably mounted, on a fixed guide rod 29,

(Fig. 2) andon the shaft 2|. The carriageend frame members one of which. is indicatedatfii! inFig. 2, are slidably mounted on the shaft2l andupon the guide rod ZB, and engage the end of the drum 24, and'cause this drmnjto partake of thereciprocating movement of the carriage.

ihe lowerpart of the carriage 30 carries a rack bar 35 meshing with a pinion 36 (Figs. 1 and- 3) r onthe upper end of a-vertical shaft 31,,which carries atits lower end a mangle geardll. ,TIhe

mangle gear is driven by a pinion 4|, shaft 42',"

horizontal shaft 45, and a pinion indicatedlgen H and 41 meshing, with the gear 26 ig. 1). The dye spool 55 is retained at its opposite ends by arms (of which one is shown in Figf '2) pivotally mounted at 49 on the ndframe members of the carriage, so that the barrelof the spool is driven through the the friction drive drum 24.

i The effect of this mechanismiis tostraighten out the fibers in the gilling apparatus and to wind these straightenedfibers undertension in spool.

In the said AbbottPatent N0. 1,797,393,the' pinion was a plain pinion faston theshaft 45, sothat the effect of the gearing such as abovedescribedwas to reciprocate the carriage V 30. at a constant rate of speed directly pro-- portional to the surface speed of the package drive drum 24. f

'- While in the machine rectly proportional tothe surface speed of the package-driving drum 24 and that of -the windingpackage, the machine of the present invention imparts to-the carriage 30 and winding spool a traversing motion which is substantially proportional to the angularvelocity 'of the wind T OFFI CE erally at. 46. Pinion 46 is drivenbyidler gears w llnd t? bit the form of a cross-wound. sliver uponthefdyei of said Patent No.

1,797,393 the traversingmotion of the carriage" and winding spool was i at a constant speed dijust the machine so as to lay each'turn of sliver I approximately four inches from the next underlying preceding turn.

Instead of driving the shaft 45 (which in turn operate the traverse mechanism) by a simple pinion which merely transmits vthe movement of gear 41 as in theisaid patent, the pinion 4 6 in the machine of this application is preferably constructed in the form of a friction clutch having regulating mechanism for adjusting its effective transmission oi driving force in accordanc with the momentary angular velocityroi the winding package.

..As inPatent No. 1,797,393; the spool-holding arms 50 are each provided with a boss 58 (Figs.

2 and 4) for the reception of a shaft fil adapted to slide axially and also to rotate in abore-in the boss 5B A flanged head member 60 frictionally engages "the-endofthe tubular spool 11191 3334 theshaftifi'fl at on side or the machine is hollow nd vna' e e shafts v Fig wh nets 'mli ber 9L naxially extending inner ch iskeyed at H to the with the head member and $1 0 5 The pulley snvssfsybelt 13- whi hptu ns pin-1 4 wh ten iss lined, t a otatab n-" eciproosting ha t .15, A" brack t 1.6 tra elin w the. earri se fifl'shi tsithe p ey it alo g t e hat- 1 5 as t e s wage recipro 'a s T e haft 15 is. thusd i v n at a speed wh ch is proportion l o hemomen ary an lar -Y-1Q py1 f the windin 'paokase. p ed progre sively d m n sh ng as the angular velocity of the winding package diminishes du n the wind n Reter ins t the iht seni ofushaft grand carries fast thereon the a Sl eve. l- ,Ih left than sleeve 81 is in vform of a plate 8| carrying a friction disl; 8 2

In practice, itis preferred to adof sprocket continually decreases during the winding so that its tendency is continually to lag behind the pinion 46 which is driven in the same direction at a constantspeed faster than any speed-attained by the sprocket 85. This lag ging of the sprocket 85 causes it to screw itself to the right along the sleeve 80, relieving the pressure (it-the bearing 90. 1; the pinion 45, thus allowing the friction clutch to slip. This movev winding. Thus the rate of reciprocation of the carriage 33] is =.continuously maintained proportional to the angular velocity of the winding package.

It will he observed that in the above-described preferred'iorm of variable-speed drive for the traverse device, the frictionally. rotated winding spool'BB is not relied :upon to supply the energy for driving the traverse device, but is merely en ployed-to control the speed at which the traverse device is driven. Very'little energy is required to drive the pinion and its driving parts i rom the'winding spool, so that the use of this device does not add substantially to theloadofdriving the winding spool. J 1

Inaddition to producin -a :more evenly wound dye package, with the turns of sliver distributed according to a definite 'pattern, the invention has the further advantage of winding with a sharper pitchat the bar-rel of the spool than at the outside-of a fullpackage. This winds the yarn more firmly on'the'barrel of the spool, without the useof such expedients as springs or weights to loa'd the-spool when winding -at'ang1 near -the'barrel.
